HEAT :DISTRIBUTOR FQR AUTOMOBILES.

Application filed June 10,A 1926, Serial-No. 115.010.

relatively large foot warming area adapted to be connected at one end to a heating device of anyA type and deliveringthe heated air at the opposite end adjacent the seat of vthe driver.

Another object' of the invention is to provide a heat distributor for motor cars adapted to replace one of the floor boards of the car body, provision being made for quickly attaching the device in operative position.

It is a more specic object to provide such a device comprising a relatively thin heating chamber adapted to be disposed transversely of the body of a motor car having superimposed thereabout a protective grid upon which the occupants of the car may support y their feet andhaving an outlet adjacent one end adapted to deliver a blast of h-ot air adjacent the seat of the driven These and other objects of the invention will be apparent from the following description made in connection with the accompanying drawings, wherein like characters refer to similar parts throughout the several views, and in which Fig. 1 is a vertical section taken through the forward end of an automobile body, showing my device applied to the Hoor boards below the pedals;

Fig. 2 is a plan view of a preferred embodiment of the device,

Fig. 3 is a section taken on the line 3-3 of Fig. 2, and

Fi g. 4 is a fragmentary cross section taken on the line 4-4 of Fig. 2.

In Fig. 1 a preferred embodiment of the invention .is shown mounted in the inclined foot board of a. motor vehicle and connected to a typeof automobile heater, such as that disclosed in my pending U. S. application,y

entitled Heating device for automobiles, S. N. 4293, filed January 23, 1925. The body of the motor car is indicated by the numeral 5, having therein the usual drivers seat 6, floor board 7 and the inclined floor board or foot board 8.

About the exhaust pipe 9, an automobile heater 10 is provided delivering at its forward end through outlet pipe l()a to my heat distributor. It is of course understood that my device may be usediwith. any type'ofl:

automobileheater whether mounted on the exhaust pipe or manifold of the engine.

In thepreferred embodiment of the invention illustrated, an elongated rectangular` casing designated as an entirety by the letter i' A is provided, formingk a thin heating chamber of considerable length and width. Casing maybe formed in any desired manner and lshere shown ascomprisingupper and respectively, lower member 12y having its side and end edges bent inwardly uponrthe body thereof and upwardly to. form the upstanding rectangular lip 12aL and the doulower rectangular shell members 11 and 12 bled flange 12b, Upper shell member 11 has .f

a rectangular depending lip 11a telescoped `with lip 12a c-o-operating therewith to'form ably covered with a layer 18 of 'some nonn;

conductive material, such as asbestos to prevent the radiation of heat from the lower `portion of the casing. A foot' supporting grid or register 14 having a reticulated body is superimposed about the top ofcasing A, i.:

spaced a slight distance .thereabove. -Regis ter 14 has its sides ldownturned to form the flanges 14, the edges of which contact the flange 12b of the lower shell of lthe casing, thereby spacingthe register and casing thev proper distance apart.- j Y Adjacent one end of casing A, an air intake B 'is formed through the lower shell member 12 in posit-ion to be connected tothe delivery end of the heater 10. 4A discharge opening C is formed adjacent the opposite end of casing A`tlirough the top shell 11, adapted to deliver a blast of hot air adjacent the feet of the driver.

' A valve 17 preferably of the sliding type.

to, moreover, deliverV a blastl of air adjacent one end of the casing. Preferably the area of slots 18 and 19 is equal to approximately twothirds of the area of the discharge openA ing C. i

The deviceis substituted forlone of the foot boards of the automobile body, preferd ably the foot board below thedriving pedals and is attached to the supporting strips 15 in the same manner as the floor boards.

The register 14; has its end portions downturned and outturned to form the horizon,

taly flanges 14D adapted to lie flush against the end portions of the flanges 12' of the lower shell section. Screws 16 may be employed to securejtheends of the device to the supporting'vstrips 15 .(-see Fig.` 3).

It vill be seen that the heated air will be delivered to casing 8 at the end adjacent the errhaust and Vwill slowly passy through the casing,heatingr the upper shell 12 and caus- "the radiation and transmission of a considerable amount of heat throughv register 14.

yA relatively small blast of heated air will be delivered through the slot-s 18 Vand 19 adjacent the intake endof the casing A, while the 'remainder offthe heated air passing vthrough the distributor will be delivered upwardlythrough Vdischarge passage C, disA posedA slightly below the foo-t pedals of the motor vehicle. The amount' of air passing through the casing can, of course, be `regulated by slide Yvalve 17. The slots 18 and 19,

` therefore, perform two functions in accomthereof.

modating the valve operating handle 17a and j passages.

From theforegoing `decriptiomit will be seen that Iliave invented a simple but highly efficient heat distributor capable of being readily attached to standard motor vehicles, and adapted to insure the comfort of the passenger Vin cold weather.

It will, of course, be understood that various changes may be made in the form, details, arrangement and proportion of parts vention,

wWhile the embodiment of the invention illustrated is adapted to be substituted for lone of the foot boards on thebodyvof an autoiiiobile,it is of course obvious that the deviceinay be attached to one of the foot without depai'tingfrom the scope of the in- 'boards' orotherwise supported on the automobile body and will function in the manner described.'

Vhat is claimed is u i 1. A heat distributor for an automobile having in combination a radiating` chamber comprising a relatively shallow shell mem- #discharge aassae'es.

ber adapted to be disposed transversely across the body'of a motorvehicle adjacent i the floor boards thereof, and an upper rel,V

ativelyshallow shell member telescoped with said lower member, said lower shell member having an` intake passage adjacent one end thereof adapted to be connected to an automobile heater, said upper shell member havinc' aV discharge passage throughV the top Vthereof and adjacent the opposite end of said chamber, a valve disposed adjacent said intake' passage land `means* for securing Asaid chamber to .the supporting means for the flo-or boards vof the vehicle. y

2. Thelstiuct-ure set forth in claim 1, said valveV having van `operating handle extending through the top of said casing.

A heat-distributor for an automobile having in combination a box like casing adapted to be disposed intake passage ladjacent one end of said casing adapted to 'be connected to anautomo- Dile heater, discharge passages through the" top of said casing, one adjacent each end thereof, and said casing having a substantial amount of radiating surface. between said "4. fi heat distributor pted to be disposed transversely of an automobile body adjacent the floor boards,
